Charges registered against a UK company at Companies House — mortgages, debentur
Charges registered against a UK company at Companies House — mortgages, debentures and other security — with dates, classification, particulars and the persons entitled. Register-wide outstanding/satisfied/part-satisfied counts lead the answer, and each charge carries a derived is_outstanding because the register records discharge under two status keys. Use when: Establish whether a UK company has outstanding security over its assets, and who holds it.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
